Improvements and fixes

A combiner box's figures open again. Deleting a plant's remote access now asks for its name to be typed first.

• Deleting a remote-access server or a connected site now asks for its name, and the warning states that its keys are gone for good.
• A combiner box's figures open again instead of failing with an error.
• A connected site that has been deleted no longer counts in the plant's remote-access status.
• When plant documents are uploaded, the suggested installed capacity now covers every construction phase, and the grid operator and planning company are recognised more reliably.
• A subnet typed but not added to the list now triggers a warning instead of the connected site being saved without it.
• Times from late yesterday no longer show as today, and dates written in words now follow the calendar day.
